1. When using the Ballard gestational assessment tool on a newborn, which of the following tests should be performed after the first hour of birth, allowing the newborn to recover from the stress of birth?

• A. Arm recoil
• B. Square window sign
• C. Scarf sign
• D. Popliteal angle

Correct answer: A

Rationale: The correct answer is Arm recoil. Arm recoil is slower in healthy but fatigued newborns after birth, making it best elicited after the first hour of birth when the baby has had time to recover from the stress of birth. This assessment helps evaluate neuromuscular maturity in newborns and is more accurate when performed after the initial recovery period. The other choices, Square window sign, Scarf sign, and Popliteal angle, are not specifically assessed using the Ballard gestational assessment tool and do not relate to the recovery period after birth.

2. What is the appropriate amount of fluid to be administered per hour using an infusion pump?

• A. 108.3mL
• B. 68.75mL
• C. 58.3mL
• D. 1400mL

Correct answer: A

Rationale: The correct answer is 108.3mL. This amount is calculated based on the total daily fluid requirement, ensuring a consistent infusion rate over the hour.

3. What is the appropriate ventilation rate for an apneic infant?

• A. 8 to 10 breaths/min.
• B. 10 to 12 breaths/min.
• C. 12 to 20 breaths/min.
• D. 20 to 30 breaths/min.

Correct answer: C

Rationale: During resuscitation of an apneic infant, the appropriate ventilation rate is 12 to 20 breaths per minute. This rate helps provide adequate oxygenation and ventilation without causing harm to the infant. Choice A (8 to 10 breaths/min) is too low and may not provide sufficient ventilation. Choice B (10 to 12 breaths/min) is slightly below the recommended range, which may not be optimal for effective resuscitation. Choice D (20 to 30 breaths/min) is too high and may lead to overventilation and potential harm to the infant by causing hypocapnia.

4. Justine is admitted to the pediatric unit due to the occurrence of diabetic ketoacidosis signaling a new diagnosis of diabetes. The diabetes team explores the cause of the episode and takes steps to prevent a recurrence. Diabetic ketoacidosis (DKA) results from an excessive accumulation of which of the following?

• A. Sodium bicarbonate from renal compensation
• B. Potassium from cell death
• C. Glucose from carbohydrate metabolism
• D. Ketone bodies from fat metabolism

Correct answer: D

Rationale: Diabetic ketoacidosis (DKA) results from the excessive accumulation of ketone bodies from fat metabolism. During DKA, there is a lack of insulin leading to the breakdown of fat stores into fatty acids and their subsequent conversion into ketone bodies. These ketone bodies accumulate in the blood, leading to metabolic acidosis and the characteristic symptoms of DKA.

5. A female child, age 2, is brought to the emergency department after ingesting an unknown number of aspirin tablets about 30 minutes earlier. Her father is blaming the mother for neglecting the child while she was cooking. On entering the examination room, the child is crying and clinging to the mother. Which data should the nurse obtain first?

• A. Heart rate, respiratory rate, and blood pressure
• B. Recent exposure to communicable diseases
• C. Number of immunizations received
• D. Height and weight

Correct answer: A

Rationale: In this scenario, the priority is to assess the child's vital signs first, including heart rate, respiratory rate, and blood pressure. These data will provide critical information on the child's current physiological status and guide further interventions. Option B, recent exposure to communicable diseases, is not the priority in an acute ingestion situation. Option C, number of immunizations received, and option D, height and weight, are important but not as critical as assessing vital signs in this immediate situation.
